its a synthetic phenethylamine. it raises the body temperature to dangerous levels very easily. the recreational dose is very close to overdose. further more alot of people say that the effects are not all to pleasant. basically the cons of most phenethylamines elavated temperature, irregular heartbeat etc drastically out weigh any recreational value of this drugs. unfortionatley uninformed people have been known to sell it as ecstacy(MDMA) . as a result people will take 2 or more when 1 is more than enough causing deaths and hospitilizations.
Hey man, that PMA didn't fuckin' kill ya?
